Compared with the prior art, the above-mentioned technical solution of the utility model has the following advantages: the ball mill in the utility model is a cylinder that is recumbent and rotates around an axis, and there are stone (porcelain) balls or steel balls inside. During the rotation, the balls with abrasives are raised and rolled down during the rotation, and the friction and impact between the balls separate the pigment aggregates when they are rolled down. Especially the impact has a dispersing effect on the sintered aggregates, and is used for grinding and pulverizing pigments that are difficult to disperse. When the ball mill is working, the grinding medium and the material in the body are lifted to a certain height with the rotation of the cylinder, and due to gravity, they fall away from the cylinder wall and fall along a parabola. The impact of the material on the grinding medium and the rolling and sliding of the grinding medium are generated Crushed by friction and shear. The ball milling process is carried out in a closed cylinder without harmful gas emissions, which is suitable for environmental protection; the screening and grading system includes multi-stage sieving and grading devices suitable for series connection to achieve grading and sieving.
